Specification of Letters Patent.

latentedie gv1.6 9 6- To all whom it concenm Be it known that I, .FRANKS. MANTON, a citizen of the UnitedSta-tes, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Anchors; and I do hereby-declare the following to be afirll, clear, and exact description of the invention, such as will enable others skilled in the art to which it .appertains to make and use the same.

My invention relates to improvements in anchors.

It has for its object to provide an anchor of simple construction, durable, and com paratively cheap of manufacture, the constructionof whichinsures its firm engagement with the bottom no :matter how it falls, renders it self-cleaning, and provides for its lyingmoreclosely to thelhull-iwhenstowed than the present Babbitt anchor.

The invention consists in .thedetailsofconstructioniandcombinations of parts hereinafter described, and more particularly pointed out in the claims concluding this specification.

In the accompanying drawings, illustrating the preferred embodiment .of my invention, Figure ,1 is a .plan view of an anchor made in accordance with my invention, the concealed :parts being shown in dotted dines. Fig. 2 is an edge view thereof, part of the shank .being'broken away. Fig. 3 is a bottom end view. Fig. 4 is a view looking downat the upper side of the mushroom or head, with theshackle 2 and pin 6 removed to shoW the lugs 4 in dotted lines; and Fig. 5 is a broken sectional view on the line :0 axof Fi .3.

INhile .the preferred embodiment of my invention is illustrated in the accompanying drawings and its construction and operation are described in this specification, the right is reserved to make such changes from the construction shown and described herein as the scope of the claims hereunto annexed will permit.

In carrying out my invention I form the entire mushroom or head and flukes integral. The bottom of the head or crown is rounded to cause the anchor to turn over on one side when it falls on said bottom. Said. head is formed somewhat after the fashion of a mushroomanchor; hot it is scallopederound its edges, With preferably four. roiectingiportions or shoulders, the two w, chrextendat right angles to the flukes heingicurved vto form sort of hooked edges adapted toiengage with the bottom as wellas said fiukes. z'zlihe flukes extend from the .centeriof the other two shou d r portions i th .usual ma l-ne The middle portions .of the firstanentioned projecting portion are reinforced nea th center of the head and aretprovided with slots ,or recesses for pivoting the shank theret 'lheiportionsrof theihead fromth sca lops to th angl s between-th fink and the reinforced portions ,ofthe other ,projeqtill'g shoulders are dishedrcut, I crming pockets provided with perforations at their ilowest points, throug wh h any mudwvhieh m y have accumulated in said pockets is washed as said anchor is hauled. *Theshan li tinsertedithrough the hearing-is etfrc itheihettom of the head and isprcvided with oppositely-projecting Jugs adapted to. e gage-the base .of said ibeaningarecess,forming theipivotal connection between the shan rand the head, said shank -,extending -.th cugh a ,restrieted [opening th ough the uppe surfa of said head. The ,edges at-theglower er dnof the shank from the ipivotwlug to he .en ar preferably beveled of an are adapted to engage the opposite y-in ined ex remities :Q

the slot .in which it 'works ,in;the head, said oblique .or inclined ,--su ac.e being so formed as to permit of the fluke iefthe head turning to anrangle of fifty degrees with the shank. The shank is retained i engagement with the headiby. lpi i serted:thrcughthe former just above the iuppers rfac of th head Referring more particularly ,to the .'d1?aw ings, '1 is the shank provided with the usu shackle and pin 2 and .3, respectively. {The oppositely-projecting lugs 4 may beforged or cast asa part of 1theeih nkio th y may be formed by forcing a pin through the shank.

. The lateral edges of said shank are beveled off at 5, and the pin 6, preferably made of steel, is inserted through the shank after it has been passed through the head. Said head has four scallops 7, each arranged between two of the projecting portions or shoulders. The flukes 8 extend from two of said 1projecting portions 9, and the other two shou der portions 10 are hooked, as at 11. The reinforced portion 10 of said shoulder is provided with the slotsor recesses 12 for the lugs 4 of the shank and recess 13 for the movement of the end of the shank. The bottom of the head is rounded, as at 14, and the upper surface 15, between the flukes at each side of the shank, is also rounded to permit of the free movement of the pin 6 as the head turns upon said shank. The pockets extending from the scallops to the angles between the flukes and the reinforced portions 10 of the shoulders 10 are designated at 16 and the perforation therein at 17. The edges of the fluke-carrying portions 9 are flattened, as at 18, to prevent the anchor from indenting the hull in stowin All edges, such as 19, of the other shoul ers 10 are well rounded in order to prevent any chance of the chain becoming fouled.

It will be noted that as the spread of the flukesthat is, the space between their adjacent edges 20, Fig. 1-is greater than the width of the shoulders 10 said flukes will not interfere with said shoulders catching upon a 1 hard resisting-surface when the anchor is being dragged. When either of said shoulders do strike, the tendency is to throw the flukes downward, so as to bring them also into engagement with the bottom. Attention is also called to the provision whereby the flukes are adapted to assume an angle of fifty degrees with the shank. This an le conforms more nearly to that of the o dfashioned stock-anchor and is believed to be a great advantage over the present stockless anchor. This angle of movement may be secured by beveling the end of the shank, as well as the extremity of the recess, as shown and described, or by arranging the end of the recess at a greater angle than shown, when the edges of the shank need not be beveled. The flukes and head being all cast in one piece in this anchor does away with the objectionable feature of the present Babbitt anchor, in which the flukes are cast separate and when assembled are riveted together, which is much more costly than my improved type. The scallops are adapted to receive the hawse-pipe flange or head as the anchor is stowed in position, allowing the anchor to lie more closely to the hull than in the present Babbitt anchor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1 ."In an anchor, the combination with a scalloped headiece having two oppositelyextending shou ders carrying flukes and two other hook-shaped shoulders extending in opposite directions at right angles to the plane of said flukes, of a shank having pivotal connection with said head-piece, the outer edges of all of said shoulders being rounded, the lateral edges of the hooked shoulders also being rounded but the lateral edges of the fluke-carrying shoulder being flattened for the purpose specified.

2. In an anchor, the combination with a scalloped head-piece having two oppositelyextending shoulders carrying flukes and two hook-shaped shoulders extending in opposite directions at right angles to the plane of said flukes, said head-piece having a series of perforated pockets one arranged opposite each scallop and between adjacent shoulders, of a shankv having pivotal connection with said head-piece.

3. In an anchor, the combination with a head-piece having flukes and provided with a recess extending from its under surface and a slot from said recess through to the upper surface thereof, of a shank extending through said slot and having oppositely-projectin lugs en aging said recess and a pin in said shank aiove the rapper surface of said head-- piece whereby sai shank is retained in connection with said head-piece.

4. In an anchor, the combination with a head-piece having flukes and provided with a recess extending from its under surface, an arcurate slot extending from said recess through to the upper surface of the headpiece, and an arcuate passage or way extending laterally from the innermost extremity of said recess to the under surface of the headpiece, of a shank extending through said arcuate slot and having oppositely-projecting lugs pivotally engaging said recess, an ex-i tended end adapted to work in said arcuate passage or way in the lower portion of said head, and a pin in said shank above the up-- per surface of said head-piece and extending across said arcuate slot whereby said shank is retained in pivotal connection with said. head-piece.

In testimony whereof I aflix my signature in presence of two witnesses.

FRANK S. MANTON.
